43300 Pneumatic Fan Clutch Wrench Set Removal Steps:
1.You should leave the serpentine belt on in order to loosen the fan clutch;
2.Choose the correct size wrench and place it on the fan clutch;
3.Place the straight pneumatic extension on the wrench;
4.Place the 3/8 drive deep socket on the end of the pneumatic extension.The socket is used to protect the end of the pneumatic extension from the hammer blows you'll need to give it to loosen the fan clutch;
(Tip: If you do have an impact air hammer (pneumatic hammer), you can skip step 4, since you can now use the impact air hammer instead of a hammer and 3/8 drive socket.)
5.With your hammer, hit the socket placed over the pneumatic extension end. The idea here is to hammer the fan clutch tool so that it will rotate the fan clutch counter-clockwi.
